UNITED STATES PATENT QFFICE.

MORITZ LAEMMEL, OF BAY RIDGE, NEW YORK.

IMPROVEMENT IN PRODUCING COLORED PRINTS ON PAPER AND OTHER FABRICS.

Specification forming part of Letters Patent No. 116,720, dated July 4,1871.

To all whom it may concern:

Be it known that I, MORITZ LAEMMEL, of Bay Ridge, in thecounty of Kingsand State of New York, have invented a new and useful Improvement inProducing Colored Prints; and I do hereby declare the following to be afull, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same.

This invention consists in printing many-colored designs at oneoperation by means of a block made in sections, each section.corresponding to one of the colors of the design to be produced, sothat, when said block is depressed on paper or other material, eachsection of the same will produce an impression in that color which itrepresents. The block used in carrying out this invention is, bypreference, composed of sections made of resin, colored as required, andbrought in the required shape by dies or molds corresponding to thevarious designs to be pmduced.

In carrying out my invention I take resin, heat it, and thin it withspirit of turpentine; then I mix the mass with coloring matter, oneportion being made blue, another red, another green, and so on accordingto the work to be produced. After the coloring matter has been uniformlymixed with the solution of resin I evaporate the spirit of turpentine tosuch an extent that the colored resin assumes the state of hardbees-wax; then I heat it slightly and form the various colors in blocksof the desired shape, and these blocks I combine into one block, whichis set in a metal frame of the required form. The block thus producedshows on its face the color of all the sections used to form the same,and when this face has been ground oii' the block is ready for printing.

The paper on which I print from my combination block is slightlydampened with spirit of turpentine, and when the face of the block isdepressed on the dampened paper the coloring matter adheres to the paperand a print is produced showing all the colors on the block. The metalframe which embraces the printing-block must be so constructed that itslides back as the block wears off. The surface of the print may beprotected bya coat of albumen or other suitable material, so that spiritof turpentine will 'not wash off the color.

It is obvious that other materials might be used for preparing theblocks besides resin 5 and I do not confine myself to any particularmaterial, though I find that a block prepared as above described gives agood result.

'VVhat I claim as new, and desire to secure by Letters Patent, is

l. A block for printing many colors at one operation, said block beingproduced of sections made of resin, colored as required, and brought inthe required shapes, all as set forth.

2. The method, herein described, of printing many-colored designs at oneoperation by means of a block made in sections, each sectioncorrespondin g to one of the colors of the design, substantially asherein set forth.

. MORITZ LAEMMEL.
